Arthroscopic Bone Marrow Aspirate Concentrate Harvesting From the Intercondylar Notch of the Knee.

ABSTRACT: Bone marrow aspirate concentrate is commonly harvested to obtain mesenchymal stem cells, progenitor cells, and growth factors. The iliac crest is the most common donor site for bone marrow harvesting and is associated with donor site morbidity of an additional incision and pain from the harvest. Iliac crest harvesting can be cumbersome because it often requires different patient positioning from the surgical procedure and additional sedation or anesthesia for the harvest prior to repositioning. The purpose of this Technical Note and accompanying video is to describe a technique to arthroscopically aspirate bone marrow from the intercondylar femoral notch, reducing the need for iliac crest harvesting.

Project description:PurposeTo assess the postoperative objective, subjective, and functional outcomes as well as complication rates in osteochondral defect patients treated with bone marrow aspirate concentrate (BMAC) and cartilage-derived matrix (CDM) during knee arthroscopy.MethodsA retrospective chart review was performed for patients treated arthroscopically with BMAC and CDM between August 2015 and August 2018 and had more than 1-year follow-up. Demographic factors such as age, sex, body mass index, and comorbidities were collected for all patients. Size and location of the osteochondral lesions also were documented.ResultsA total of 14 patients were identified with a mean follow-up of 19 months. On average, patients were 34 years of age (range 16-58 years) and 43% were female. Postoperatively, knee flexion increased by 8° from 124° to 132° (P = .002). All patients regained full extension; however, 1 patient later acquired a 2° extension contracture after a traumatic event. The average hamstring strength significantly increased from 4.1 to 4.6 postoperatively (P = .33). The average quadriceps strength significantly increased from 4.0 to 4.5 postoperatively (P = .007). Mean visual analog scale scores significantly decreased postoperatively (4.5 vs 1.4; P = .001). There was a significant increase in Knee Outcome Survey Activities of Daily Living scores (53.8 vs 92.9; P = .007). Mean Knee Outcome Survey-Sports scores also increased, although this was nonsignificant (28.2 vs 79.5; P = .560). No significant differences were noted in pain and functional outcomes when stratified by the osteochondral defect size and location. Complications included a stitch abscess, Baker's cyst, and residual pain treated with hyaluronic acid injection.ConclusionsThis study demonstrated arthroscopic BMAC and CDM implantation appears to be safe and has the potential to improve patient outcomes in the short-term postoperative period.Level of evidenceIV, therapeutic case series.

Project description:PurposeTo evaluate short-term outcomes for the biologic treatment of bone marrow edema (BME) of the knee using bone marrow aspirate concentrate (BMAC) and injectable demineralized bone matrix (iDBM).MethodsWe performed a review of prospectively collected data from patients who underwent treatment for bone marrow lesions (BMLs) of the knee using BMAC and iDBM (IntraOsseous BioPlasty; Arthrex, Naples, FL) between May 2017 and December 2018. Inclusion criteria included patients aged 18 to 65 years with the presence of BME on T2-weighted magnetic resonance imaging in the subchondral weightbearing region of the tibia or femoral condyle, with pain corresponding to the same compartment. The International Knee Documentation Committee (IKDC), pain visual analog scale (VAS), and 12-Item Short Form Health Survey (SF-12) scores were used to evaluate clinical outcomes.ResultsWe evaluated 20 patients who were treated at a single academic medical institution over a mean 14.5-month follow-up (median, 14 months; range, 6-25 months). The average patient age was 51.7 years (range 38-62 years). Compared with preoperative values, the visual analog scale decreased from 7.0 to 1.3 (P = .008). The mean International Knee Documentation Committee scores improved from 29.2 to 66.1 (P = .063). Both the Physical and Mental Component Scores of the 12-Item Short Form Health Survey also showed improvement (Physical Component Score, P = .438; Mental Component Score, P = .563). Based on postoperative magnetic resonance imaging, 75% (3 of 4) of the BMLs demonstrated complete healing. The survival rate was 93% at 1-year follow-up.ConclusionBiologic treatment of BME of the knee using BMAC and iDBM is an effective adjunct to arthroscopy that provides short-term pain relief for BMLs associated with degenerative conditions of the knee. This procedure is associated with clinically significant improvements in knee pain and function at a short-term follow-up.Level of evidenceLevel IV, therapeutic case series.

Project description:Background: In the last decade, regenerative therapies have become one of the leading disease modifying options for treatment of knee osteoarthritis (OA). Still, there is a lack of trials with a direct comparison of different biological treatments. Our aim was to directly compare clinical outcomes of knee injections of Bone Marrow Aspirate Concentrate (BMAC), Platelet-rich Plasma (PRP), or Hyaluronic acid (HA) in the OA treatment. Methods: Patients with knee pain and osteoarthritis KL grade II to IV were randomized to receive a BMAC, PRP, and HA injection in the knee. VAS, WOMAC, KOOS, and IKDC scores were used to establish baseline values at 1, 3, 6, 9, and 12 months. All side effects were reported. Results: A total of 175 patients with a knee osteoarthritis KL grade II-IV were randomized; 111 were treated with BMAC injection, 30 with HA injection, and 34 patients with PRP injection. There were no differences between these groups when considering KL grade, BMI, age, or gender. There were no serious side effects. The mean VAS scores after 3, 7, 14, and 21 days showed significant differences between groups with a drop of VAS in all groups but with a difference in the BMAC group in comparison to other groups (p < 0.001). There were high statistically significant differences between baseline scores and those after 12 months (p < 0.001) in WOMAC, KOOS, KOOS pain, and IKDC scores, and in addition, there were differences between these scores in the BMAC group in comparison with other groups, except for the PRP group in WOMAC and the partial IKDC score. There were no differences between the HA and PRP groups, although PRP showed a higher level of clinical improvement. Conclusions: Bone marrow aspirate concentrate, Leukocyte rich Platelet Rich Plasma, and Hyaluronic acid injections are safe therapeutic options for knee OA and provide positive clinical outcomes after 12 months in comparison with findings preceding the intervention. BMAC could be better in terms of clinical improvements in the treatment of knee OA than PRP and HA up to 12 months. PRP provides better outcomes than HA during the observation period, but these results are not statistically significant. More randomized controlled trials and high quality comparative studies are needed for direct correlative conclusions.
